Research and development of labview based virtual oscillograph .

基于labview的虚拟示波器设计与开发。

Main outcome measures : waveshape was observed through the use of storage oscillograph and corresponding data were recorded . Frictional force was determined and compared .

主要观察指标：在存储示波器上观察波形并读取数据，测出各组摩擦力进行比较。

According to the result of experiment , two appropriate ways : oscillograph method and galvanometer method were advanced to adjust the converter feed , so that the quality of wire cut edm could be improved .

通过实验结果观测分析，提出在线切割加工中，利用示波器法和电流表法来合理调整变频进给，从而提高加工质量。
